| Abstract |
The preference-avoidance reactions of the crayfish, Cambarus acuminatus, exposed to nominal cadmium concentrations of 125.0, 12.5, and 1.25 µCd++/ l are examined. Pooled data from five trials at each treatment concentration demonstrate a statistically significant avoidance of the highest concentration, and preference for middle and lowest concentrations. Additional observations of behavior indicate that crayfish sense sublethal cadmium concentrations and respond to them with a general decrease in activity. Therefore, the use of crayfish locomotor activity as a potential parameter for continuous biological monitoring systems appears feasible. |
